thermodynamiC ProPerties as a funCtion of temPerature

l. V. Gurvich, V. s. iorish, V. s. yungman, and o. V. dorofeeva

The thermodynamic properties C°

(T), S°(T), H°(T)-H°(T

-[G°(T)-H°(T

)]/T and formation properties ∆

°(T) are tabulated as functions of temperature in the range

298 .15 to 1500 K for 80 substances in the standard state .The ref-

erence temperature, T

, is equal to 298 .15 K . The standard state

pressure is taken as 1 bar (100,000 Pa) . The tables are presented

in the JANAF Thermochemical Tables format (Reference 2) . The

numerical data are extracted from IVTANTHERMO databases

except for C

are based upon TRC Tables . See the references for information on

standard states and other details .
